They are completely neutral. They don't have either good nor evil intentions. They are summoned, a contract is formed and they carry on with their work of fulfilling it. After it's done they get their payment, the soul of the one who summoned them. Tell me, is the firing squad evil? Was the executioner during medieval times evil? Are soldiers evil? Are hit men evil?

basically your saying that unless required by their job, they doesn't actively go about killing people, and even when they're on the job, they're doing it in a professional manner unlike trigger or knife happy psychopaths.
at least that's what i think you mean.
